Finally, after 7 times trying for the worm-eating warbler, I heard and saw it at 7:30 am at the croton/Shimek unit 3 miles west of Argyle. At the first creek crossing instead of going left over the main creek, go right, through the brush, and follow the smaller creek up to the wooded canyon. This is where the bird was. It was approx. 20 yards up the canyon.
